Red Sox's Ortiz on what it takes to go from worst to first

David Ortiz, just named the World Series Most Valuable Player, says a simple recipe took the Red Sox from one of their rockiest seasons in history in 2012 to a World Series victory in 2013.

"We have an unbelievable manager, and guys with big hearts," Ortiz told CNBC. "That's all it takes."

It was also special to take the trophy back to Boston in the same year the bombing at the Boston Marathon rocked the city, he said.

"I'm from the Dominican Republic, and baseball is very intense over there," he said. "And every time you play in Fenway, every time you're dealing with the Red Sox fans, it's the people that have the true love for baseball, and to me, it gets no better."
